Title: Endoscope instrument
Inventor: NISHIYAMA MASAHARU
IPC: A61B1/00
Filed: 1987-10-17
Abstract: PURPOSE:To execute the observation of a wide range and the observation of an enlarged image by one endoscope by leading the observed images which have been converged by plural lenses whose focal distances are different, to a single image pickup means, respectively and cutting off alternatively an optical path from each lens between an object and the image pickup means. CONSTITUTION:The first refracting prisms 2 (2L, 2R) catch an image of an observation part 3 by separating it into L and R images, and they are refracted so that optical axis Li, Ri of the respective images of L and R become parallel to each other, made incident on lenses 5L, 5R and made incident on the second refracting prism 6, and the second refracting prism 6 leads them to the light receiving surface of a solid-state image pickup element 7. In this case, as for the lenses 5L, 5R, the focal distances are different, respectively, and the observation part 3 can be observed extending over an enlarged or wide range. Also, on each optical axis between the second refracting prism 6 and the solid-state image pickup element 7, electronic shutters 8L, 8R for constituting a light shielding means for light-shielding alternatively and L side and the R side are provided, and can be brought to opening/closing driving arbitrarily by a changeover switch 12a. In such a way, observed images consisting of different enlargement ratios can be obtained easily.
